type with perforated faces, for automobiles,-

ind is designed for use at either the front or rear of the automobile or'other vehicle upon which it is to be used.

By the utilization of our invention in connectien with automobiles We are enabled to provide a signal lamp that is extremely siniple in construction and operation, comparatively cheap in cost, but is a comparatively perfect instrumentality for performing the functions of indicating to a succeeding vehicle the direction in which the preceding vehicle, (or when the vehicle carrying the lamp) is about to make a turn, and the lam also utilizes colored lights, red for the tail 7 light and green when the signal lamp is used at the front of the automobile.

The invention consists in certain novel combinations and arrangements ofparts as Y hereinafter more fully set forth and claimed.

In the accompanying.drawings we have illustrated one complete example of the physical embodiment of our invention constructed according to the best mode we have so far devised for the practical application of the principles of the invention.

Figure 1 is a front elevation of the signal lamp.- Fig. 2 is a top plan view. Fig. 23 is a side elevation. Fig. l! is a sectional view at line AA Fig. 1. Fig. 5 is a view of the housing. boxes, open.

In the preferred embodiment of our invention we employ a housing 1 preferably mhde up of suitable metal and rectangular in shape, and adapted to inclose the electric lamps as 2. Q, and. their sockets 3, 3, etc.

In the bottom wall of the housing a plug ei is lined for the wires which convey the.

electric current to 'tlfe lnmps 2, and on the rear Vllll of the housing. a bracket 6 is attachcd which is adapted to be pussiul oi'rr a post and secured thereto means of the set screw or clump screw 7. 'ihe post for the bracket is attached to a suitable portion of the automobile or its frame, either at the Fig. 6 is a View of one of the front of the automobile, or at the rear, an in many instances the signal lamp is used both at the trout and rear of the automobile.

, At its center in thefr'ont wall, the housing is provided with the usual bull's light as 5 illuminated by'the lump 2' in thehousing and it will be understood that this colored lump maybe red at the rear of the vehicle and green at the front for purposes well understood. V

' In the front wall of the housing. two do pressions or grooves 9 and 10 are fashioned, and in Fig. 5 particularly it will be seen that these grooves ere, each of them, of diminishing diameter in opposite directions. 'lhe ivalls of the grooves are curred or semi elliptic in cross section and the grooves are designed t reccive, ezichjoi' them, a peculiarly fashioned, tapered, signal box indirated as a whole by the numbers ill and 12.

The body of each box, as indicated at 13 is formed. to neatly fit within the recess or groove of the housing, and the boxes are held in these recesses or grooves in suitable manner. One end of the body of each iDOK is pointed as indicated at 1%, the other end being closed by the Wall l5, and an opening 16 isprovided through which the lamp sockets may project, a complementary opening lT-being provided in the wall of the recesses in the housing. The body of the box has its inner fuce or surface equipped as a reflector and it may be treated in any of a number of dili'ercut ways for accomplishing this end. To the reflector or body-portion of the box, a lid or cover 18 is hinged at 19. This cover is preferably of opaque material. being of suitable metal, and it is of the general shape of the body, '1'. c. it has a pointed end 20 and diminishes in width. or is tapered to its smaller end. I i

In the accompanying drawings we have shown'the lid or-covcr cut out in the form of an arrow as 2L but it will be understood that this design may boot other suitable forms, such as a hand with its index finger pointing in the proper direction. Ellis-space 21 is closed by :1 glass 22, and the glass, which is translucent or seuiitransparent. may be colored red and frosted for this purpose. With the lump lighted behind the (muslin-cotglass it will be readily undersl' -il lhat tho outline of an arrow, red in color. is reproduced in the front or lid the lump box. which may be used as a signal to show the direct f travel.

The two lamp boxes are alike in construc- 1 tion audit will be evident that they may be assembled in .opposite directions in the housing, with either one at the top of. the 5 housing, and when the p'roper lamp is lighted, will indicate as desired. The body part of the two boxes forms thereflectors for the lamps, and. the housing for these reflecting parts forms a covering for the lamps and 10' base or foundation for the lamp boxes. .The

' be distinguished readily atusual "distancesg lamp sockets extend through the twoopenings, one in the grooveo'r recess-wall and- I the other in the'refiecting wall of the, box, and it will be manifest that the bulbs or 1 lamps 2 may be inserted, after the boxes are }located; in place, by opening the hinged nall door or cover ofthe lamp box.. i i

The automobile is equipped with a fourpoint switchoin its lighting system-so that 9 all four indications, red, green, right,'0i: left may be made independently of each other, as the green in front and red at ;therear, may ormay-not both be in service at the same time. The front and rear lights would 25 of course have. independent switch. lev'ersor connections, but a single switch lever could be used for the right and left. lights or are rows, which of course are never-both in use at the-same time. The lights in therefieo. tors or boxes,.when. used .both'in front and 30 7 rear, are connected so that they -will be lighted simultaneously with thesingle' op orationof the lever andv both lightswill point'in the same direction; A signal lamp constructed according to 36 our inventionit'will be noted, isv especially thin and compact; but at the same time it offers large clear indicating arrows that may The conibination ina signal lamp with a recessed housing, of a pair of separable oplEmsitely pointed lampboxes fitted-in the ousing, each -lamp box having a longitudian opaque lidto each box having a trans- -parent portion forming an indicator.
